  • Abstract
    A loss-control tuning loop for Q-enhanced LC filters based on a voltage-controlled filter (VCF) is presented. The main factors affecting the tuning accuracy in this tuning scheme, including mismatches and frequency tuning errors, are discussed. The tuning scheme was implemented for a 1.5-V, 6-GHz Q-enhanced LC filter on a UMC 0.18-mum standard CMOS process. The design and measurement results are given. Effective loss control of the filter over process tolerances is demonstrated
